杨树浦电厂22号机系一台新背压机组,这次在安装投运过程中发生了推力瓦温度高、机组振动大而不稳定和盘车装置咬死等质量问题,使试运行工作一度不能顺利进行。当时,华东电力建设局一处、华东电力试验研究所及杨树浦电厂三方面既不强调客观,也不互相推诿,而坐下来共同反复商讨。经过多次试验,终于发现了推力瓦吃力不均、励磁机软轴同心调整支承块遗忘取出、盘车装置齿隙小于幌度及疏水系统接法不合理等主要缺陷,并作出了解决办法。这说明对于提高质量问题,并不是不要化一点力气,而一定要有点苦干实干精神,用科学态度,实事求是地对现场进行调查分析,才能找出真正原因和提出有效对策。
No.22 unit of Yangshupu Power Plant is a new backpressure unit. During the installation and commissioning, high quality of thrust shingles, high and unstable vibration of the unit, Smooth progress. At that time, one of East China Electric Power Construction Bureau, East China Electric Power Experimental Research Institute and Yangshupu Power Plant neither stressed objective nor promoted each other, and sat down to discuss it repeatedly. After many tests, finally found that the thrust pad uneven, concentric adjustment of the exciter shaft forgotten forgotten remove, crank gear tooth gap is less than the fair and the hydrophobic system connected unreasonable and other major defects, and made a solution. This shows that for improving the quality of the issue, it is not necessary to turn a little strength, but must be a bit hard work hard, with a scientific attitude, realistic investigation of the scene to find out the real cause and put forward effective countermeasures.
